If you have a stronger reaction to the COVID-19 vaccines, does that mean you’ll be rewarded with extra immunity?
Not necessarily, said Dr. Jim Kublin, principal staff scientist with the Vaccine and Infectious Disease Division at Fred Hutchinson Cancer Research Center, who also works with the COVID-19 Prevention Network.
That correlation may be true with some vaccines, but it does not appear to be the case with the mRNA vaccines, at least not in preliminary studies. Scientists have seen people who experience very little reaction to the vaccine but still exhibit immunity to the virus.
